My grant 70 mk 2 heating pressure is constantly increasing in pressure. I have changed the heat exchanger as I believe that was the problem. Any ideas

The filling loop is disconnected. Also the pressure drops to zero when off, and the expansion vessel is newI assume you mean you have changed the plate to plate?
Have you totally disconnected the filling loop?
Filling loop disconnected, pressure drops when boiler off, new expansion vessel, hose disconnected and blown throughThe cost of plate heat exchangers I'd want more than a belief it's at fault.
Checked the filling loops not passing?
Is it rising when the boilers off?
Pressure vessel ok?
Pressure vessel hose not blocked?
Pressure increases when heating on, drops to zero when heating offThought pressure was increasing?
Hot water is fine, even when the heating is onPressure ok when just on for hot water?
Pressure increases when heating on, drops to zero when heating off
I'll check them in the morning, thanks for replyingThen its either expansion vessel, expansion vessel connection, or where the expansion vessel is connected to boiler.
